Android Code Snippet Custom Toast Message

You can customize the toast message text with CSBuilder: https://www.b4x.com/android/forum/threads/76226/#content

This code allows you to also change the background color and the toast position:

Sub ShowCustomToast(Text As Object, LongDuration As Boolean, BackgroundColor As Int)
   Dim ctxt As JavaObject
   ctxt.InitializeContext
   Dim duration As Int
   If LongDuration Then duration = 1 Else duration = 0
   Dim toast As JavaObject
   toast = toast.InitializeStatic("android.widget.Toast").RunMethod("makeText", Array(ctxt, Text, duration))
   Dim v As View = toast.RunMethod("getView", Null)
  Dim cd As ColorDrawable
  cd.Initialize(BackgroundColor, 20dip)
  v.Background = cd
   'uncomment to show toast in the center:
'   toast.RunMethod("setGravity", Array( _
'       Bit.Or(Gravity.CENTER_HORIZONTAL, Gravity.CENTER_VERTICAL), 0, 0))
   toast.RunMethod("show", Null)
End Sub

Depends on JavaObject library

Usage example:

Sub Activity_Click
   ShowCustomToast("Testing...", True, Colors.Green)
   Sleep(3000)
   Dim cs As CSBuilder
   cs.Initialize.Color(Colors.Blue).Size(20).Append("Custom Toast").PopAll
   ShowCustomToast(cs, True, Colors.Red)
End Sub

On my Android 7.1.1 I get a square toast.
Is it possible to have rounded corners?

 

[Erel]

Try the updated code.

I had problems to get a toast message.
Afte hours of testing I found the solution.
It is necessary to activate notification for your app in the android system.

I hope this helps.

One question:

how can I cancel an activated toast message?

 

[Erel]

The toast disappears automatically after a few seconds.

You can hide it immediately with:

toast.RunMethod("cancel", Null)

Hi, Is it possible to append an image?

[Erel]

Should be possible. See CSBuilder tutorial.

Another option with more features: [B4X] BCToast - Cross platform custom toast message

I used this code, it works well on Android 7, but it gives an error on Android 11:

This will not work on latest versions of Android:

Dim v As View = toast.RunMethod("getView", Null)
  Dim cd As ColorDrawable
  cd.Initialize(BackgroundColor, 20dip)
  v.Background = cd

You can no longer access the internal toast view.

BCToast is a possible cross platform alternative.

I don't know this is a bug or not, but however `getView` and `setView` are deprecated, but `setView` still working well. i try it in android 11,12 and 13, with target 33.
I am not encouraging anyone to use outdated method, I just shared my experience with you.
Good luck
